Tarsal Tunnel Syndrome

Tarsal tunnel syndrome is a pinching of the tibial nerve, which
stretches down the back of the leg to the inner ankle. In this area of the
ankle, a complex mix of nerves, muscles, and ligaments meet; this makes the
tibial nerve prone to entrapment, or pinching.

Symptoms of tarsal tunnel syndrome include foot pain and weakness
as well as numbness and tingling in the sole or arch of the foot.

A nerve might get pinched as a result of:

An injury to the ankle.

Rolling the
foot inward when walking or running (pronation).

A tissue mass or
cyst.

An area of inflammation in or around a tendon
(tenosynovitis).

At first, treatment may include rest, anti-inflammatory medicine,
and supportive footwear, such as arch supports, custom orthotics, and support
shoes. If this early treatment does not help relieve symptoms, surgery may be
needed.
